Experimental Investigations of Temperature and Suction Effects on Compressibility and Pre-Consolidation Pressure of a Sandy Silt

Lyesse Laloui, Bertrand François, Simon Salager

Research interest in the thermo-mechanical behaviour of unsaturated soils is growing as a result of an increasing number of geomechanical problems involving both thermal and unsaturated effects. In this framework, this paper addresses a unified thermo-mech ...

The porous surface model, a novel experimental system for online quantitative observation of microbial processes under unsaturated conditions

Dani Or

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometri ...

Thermo-plasticity of fine-grained soils at various saturation states : application to nuclear waste disposal

Bertrand François

Soil is a particulate material that may undergo irreversible strain as the relative positions of the constituent particles change. That irreversible behaviour may be induced not only by an external stress variation but also by temperature or suction change ...

Mechanical behaviour of unsaturated aggregated soils

Azad Koliji

Particle aggregation is a commonly observed phenomenon in many types of soils, such as natural clays and agricultural soils. These soils contain porous aggregates, often separated by large, interaggregate pores. Two levels of intra- and interaggregate poro ...

Disturbed state concept for partially saturated soils

Lyesse Laloui, Laurent Vulliet

A general elasto-plastic model for partially saturated soils is proposed, based on the disturbed state concept (DSC). This model is unified and simplified, includes both saturated and unsaturated states and is able to capture some typical features of parti ...
